A pulsating mass of acidic protoplasm. It can and will eat almost anything, growing and splitting as it does so.

“Beware of the Blob!It creepsAnd leapsand glides and slidesAcross the floorRight through the doorAnd all around the wall,A splotch, a blotch...”-Burt Bacharach and Mack David, “Beware of the Blob”. 1958.

Useful Info

Jellies are rather weak creatures that introduce the player to the concept of corrosion, a stackable debuff which inflicts a negative slaying bonus and an AC penalty.

Followers of Jiyva will have a frustrating time with the jellies their god provides. These jellies have a special appetite for items lying around the dungeon floor and will devour anything except artefact items.

Tips & Tricks

If at all possible, you should fight jellies using ranged attacks to avoid their acid.

Wearing a ring of resist corrosion or another source of rCorr will greatly reduce the chance of corrosion, as well as the damage you sustain.

History

Prior to 0.19, jellies would eat items on the ground that the player had not seen even if the player was not worshiping Jiyva.

Prior to 0.17, jellies would also eat items on the ground that the player had seen.

Prior to 0.15, jellies were notorious for permanently weakening weapons and armour used in combat against them. The corrosion overhaul changed this.

Prior to 0.14, jellies would not split no matter how many items they consumed.

Prior to 0.13, jellies were more durable and hit harder, but only had speed 9.
